摘要

The promoter region between -330 and -280 (relative to the position of transcription start site, +1) was found to be critical for PB induction. Putative binding sites for Drosophila Broad-Complex (BR-C) and deformed (Dfd) were identified within this promoter region using TFsearch. RNA interference (RNAi) treatment of S2 cells in conjunction with CYP6D1 promoter assays showed that suppression of Drosophila HR96 and BR-C transcription in S2 cells resulted in a significant decrease and increase, respectively, of PB induction. Effects of HR96 and BR-C in mediating PB induction were PB specific and PB dependent. This represents new functional evidence that Drosophila HR96 and BR-C can act as an activator and repressor, respectively, in regulating PB induced transcription in insects.
